It turns out that I have a hard time doing a sniff, I do not know if it is properly installed, if this is executed in the correct package, or I just do not know how to do it, but I followed several instructions and examples and none of them worked for me. I throw command not found.
This is the version and the instruction that it sends me, for me to execute some command, it would be good an orientation or some help
